the surface water chemistry of thiruvananthapuram museum lake was carried out in the period of february 2013 to january 2014. correlation study of the parameters and overall ccme wqi (canadian council of ministers of the environment water quality index) was also prepared in the study for the lake water. the parameters analysed are cations such as ca2+, na+, mg2+ and k+ and the anions like po4-,...

mixed convection fluid flow and heat transfer of water-al2o3 nanofluid inside a lid-driven square cavity has been examined numerically in order to find the optimal distribution of discrete heat sources on the wall of a cavity. the effects of different heat source length, richardson number and grashof number on optimal heat source location has been investigated. moreover, the average nusselt num...

Bamdezh wetland with the geographical coordinates of   north longitude, east latitude and an area of 44 square Kilometers, is located in about 40 km northwest of Ahvaz and Shavur River is the main source of its supply. This wetland is not only a habitat and suitable food source for aquatic and migratory birds, but as well a significant resource of income for the locals. Today, with the arrival ...

magnesium hydroxide mg(oh)2 nanorods with diameters of 90±10nm and lengths of more than 2μms were prepared by a simple route at ~75oc in ambient air. the approach is based on reaction of magnesium powder and de-ionized water without the use of any harmful, toxic or corrosive reagents. characterization using x-ray diffraction (xrd) shows single crystalline structure of mg(oh)2 (brucite) whereas ...

The present study investigated NO3- and Br- contamination in groundwater of Arak aquifer, Markazi province, Iran. Correlation and factor analyzes were used to detecti nterrelations and sources of NO3- and Br- ion concentration and other physicochemical variables. No correlation was observed between NO3- and otherscontents, but a positive correlation was identified between Br-and other majorvari...

in some regions of isfahan, although there is no soil and water salinity limitations, quality of sugar beet root is very low because of using high amount of irrigation water. a study was conducted to determine the relation between low irrigation and quality and quantity of sugar beet. in this study, a line source irrigation system for six water use treatments (from 10770 to 8554 m3/hec) was use...
